Popper�s Falsifiability Criterion for Scientific Theories
General principle: In order to achieve the falsifiability criterion, a theory must specify the conditions under which it can be falsified, or proved wrong. The theory does this by generating predictions that, if true, support the theory, and, if false, discredit the theory.
Example: If finding A is observed, theory is supported .
If finding B is observed, theory is not
supported and must be revised or rejected.
Note: Predictions must be: made in advance
